With the installation of my new pullies, (from Underdogperformance) I think I have pretty much tapped out the Ranger bolt-on mod list.

Here they are in order:
1. K&N FIPK
2. E-FAN
3. JBA Headers
4. JBA Catback Exhaust
5. JBA Power Cables
6. Tuner from BamaChips*
7. Underdrive pulley (to include alternator and water pump pullies)

I can't really think of anything else without spending thousands or opening the engine. Am I missing anything?

 

You forgot the most important mod - a BamaChips tuner. Doug at BamaChips is considered to be the king of the Ford 4.0L.

 

D'oh! I have a tuner. I guess I forgot about it because I didn't get frustrated installing it.

 

So with all of these mods how much HP and TQ do you think gained.

 

I really have no idea. I don't think I will ever pay to have a dyno either. It feels more powerful, and I had fun installing everything myself. So I figure I got my money's worth

 

throttle body. Either hack your own:

or this guy modifies them for you:

that's the only other thing i could think of... after that, it sounds like your next available mod will cost a couple thousand (supercharger )

 

I've heard that roller rockers are a pretty good performance mod. I think Wayne sells them at Underdog. Check into it.

 

no roller rockers for a 4.0, just a 3.0.
